Containera of' 'which the following a ."specification `M y invention relates-to' means for roing iniammable,. explosive tluids such protective screen between the outer air and 15 the contents of the can consisting of an irregularly 'tangled mass of resllient, refractory filaments, these filaments 'each having an'extremely small'cross sectionalarea and' relatively great length. f 1

In order to producean e'ective protector, itis necessary that the materlalshould berefractory, 'as votherwise theiilaments` woiild burn out upon the application of heat," It is necessary that the material l'be 1n laf mentous form as this is the best possible form to secure a rapidfabsorption of heat withalow emission'thereof. The filaments must be resilient as this resiliency, where the filaments are irregularly tangled together in a mass, actsto hold the ilamentsseparated thereby permitting the easy 4from each other,

passage of fluidthrough the mass and, furtheremore, the resilience of the individual filaments makes the tangled mass of fila.-

35 ments resilient as a Whole and hence'p'ermits the mass to be compressed into a duct without being pressed so tightly againsteach 'v -other as to'impede'the passage ofoil or other liquids within the container. .The fila- 4Q ments must be tangled together so that they run in all directions through themass as -thereby one filament engagesgan'd '.hold's another in place and separate'filaments cannot drop out into the can. Furthermore,

this tangling o-'the filaments to ether' so that the filaments -run -in all irecti'ons .through the mass rendersthe mass elastic in l all directions s o that the separate filaments will yield to the passage 'of oil, or to thc bfpressure of an instrument and will thenv .spring back 'into'their original position and will not be: permanently f lsplaced.

refractoryi The fine, long, intermin led or tangled aments absorb heat rapi ly but have .a 'low degree .of conductivity and the individual silient and therefore'the mass of. lilaments vas a Whole is resilient so that uthe 'laments .are held separated from each 'other and Whendisplaced will'sprin'g back into their `hig heat absorbing deceive power.

these 'iilaments, the temperature is raised' only locally .and the heat-absorbing power being so eat, the heat is not transmitted to the-otbr end of the mass. In other Words, when heat is applied to one end of a tangled mass of metallic wool it is 'not power, a very low. conwer and a .very low emasslve transmitted back into the lbody of the mass.

Thisis true even where a very hi h degree of heat is applied to one end of ai mass of these laments. That Vportion ofthe mass in intimate contact with theame is highly heated, but the body of the mass is entirely cool. An embodiment of my invention is shown in the accompanying drawings.- wherein: Figure l is a diagrammatic section of a portion of a container provided with aductv lled- With a massof refractory laments.

chamber 3 is filled with a ,tangled mass ot refractory, resilient lame'nts'such as a mass v of'metallic wool, said mass being designated 5; This mass of metallic wool is shown as being lheld in position. by means of the opl positely disposed perforated or reticulated disks or plates 6. `Ilhile Figr l shows a pouring or outlet `duct,'it will be obvious that practically the same construction might bev` used for an inlet ductiwhereby airA can pass into the container. '.In'Fig. 2, however', I show a form -of duct particularly devised for permitting the entrance of air to the. container but pre- In this 'con- .venting the entrance of flame, struction, 7 designates the upper portion cfa liquid containerhaving aiiairinlet-opening 8.

I have shown a pair of these disks or plates 12 at each end of the chamber 11. It will be seen that this construction is practically t-he same as that before described. Itis simply a duct or passage having therein a filling consistin of a tangled mass of resilient, refractory laments.

It isl to be understood that .the devices shown in Figs. 1 and 2 are merely illustra tive of my invention and that the principle of the invention may bev-applied to any forni of holder or container for explosive fluids, and that any form of duct r passage may be protected by the use myl improved screen.

Having thus described the invention, what is claimed as new is:

1. A container for explosive and inflammable fluids, said container having a duct, and a filling of metallic wool disposed in the c' uct, the interstices between the filaments ot wool permitting the passage of liquid from the container.

2. A rotective screen ing exp osive, iniarnmable fluids, consisting of a resilient mass formed of loose, irregularly contacting, independent, separated ilaments of resilient, refractory material, the resiliency of the filaments separating them from each other and maintaining open passages throughout the mass.

In testimony whereof, I affix my signature in presence of two witnesses.
